[FREE] Check one x402 endpoint before you try to pay it, or check your own before you ship. Calls the URL once with no payment and grades the 402 a buyer receives: whether a facilitator is named where clients read it and whether that facilitator answers, whether the Payment-Required header exists and survives a default 4KB proxy buffer, whether the terms are complete enough to sign, and whether the price clears the measured on-chain cost of settling it, and whether the resource description is short enough to survive Coinbase CDP's /verify (a ~500-char cap past which first-settle through their facilitator breaks). Returns a 0-100 score, a verdict, and each defect with what it costs and how to fix it. url should be the full endpoint URL. method is the verb the endpoint expects, GET or POST. Free, unauthenticated, and it never sends a payment.
